Bug ID: 37915 Summary: IsWow64Process fix(es) required: 32bit UPlay games do not launch in a 64Bit prefix when Wine is set to Vista/Win7 Product: Wine Version: 1.7.34 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: abolte@systemsaviour.com Distribution: ---
While the recent commit http://source.winehq.org/git/wine.git/commitdiff/bfd088dbc6b4f397d9adfbc11a6... now allows Uplay to launch 64-bit games in a 64-bit prefix when Windows 7 is selected (and probably Vista and 8), it doesn't help with launching 32-bit games.
Since #33776 was closed without covering this situation, I'm opening this bug to cover that use-case here.
Attachment 50492 from #33776 (https://bugs.winehq.org/attachment.cgi?id=50492&action=diff) solves this for me, but seems to be a work in progress based on what the author has said there.
This issue is also perhaps not specific to Uplay, although I don't know of any other application affected by the bugs in the existing implementation at this time (hence the title).
